Capitol Dome to undergo $60 million restoration

The U.S. Capitol Dome is about to undergo a two-year, $60 million restoration project that, much like the one at the Washington Monument, will cover the iconic structure with scaffolding.

The cast-iron dome, constructed 150 years ago -- and championed by then-Sen. Jefferson Davis (D-Miss.) until he went off to run the Confederacy -- has not had a complete renovation since 1960, according to the Architect of the Capitol, and age and weather have caused more than 1,000 cracks and other "deficiencies."
